Definitions
- the present invention relates to a filter housing and a manufacturing method for a filter housing.
- the invention relates to a filter housing for an air filter for the intake air of an internal combustion engine.
- Filter housings are typically manufactured by the injection molding process. During injection molding, the upper and lower parts of the housing are manufactured using separate tools.
- the thermoplastic molding materials (powder, granules, cubes, pastes etc.) are heated to liquefaction (approx. 180 ° C) and then injected under high pressure (up to 1400 bar) into closed, two-part, steel, water-cooled hollow molds where they are cool down and solidify.
- Polystyrene, polyamides, polyurethanes, cellulose ethers and esters, polyethylene, polymethacrylic acid esters and other thermoplastics, thermosetting plastics or vulcanizing elastomers made of rubber or silicone rubber and sometimes also foamed plastics are used as molding compounds.
- EP 0726389 B has therefore already been proposed to provide part or both plastic parts with at least one channel closed on all sides, which increases the strength and the maximum bending stress.
- This channel is manufactured using the gas pressure process.
- the plastic material can first be introduced into the injection mold in a single injection molding process and then VSS 1583, air is blown into the duct to be formed through the injection molding nozzle or through another nozzle, as a result of which an air-guiding duct is formed.
- the object of the present invention is therefore to provide a filter housing and method for producing filter housings, the filter housing having sufficient tightness and rigidity and being simple and inexpensive to produce using a tool.
- the filter housing according to the invention has an upper and a lower housing part, the two housing parts being sealingly connectable to one another.
- the connection of the housing parts to each other can, for. B. generated by screws or snap hooks, of course, all other types of connection known in the art can be used.
- a seal can be arranged between the housing parts, which produces the seal of the housing parts. Here, the seal rests on both housing parts.
- a filter element can be used in the filter housing, which one of the VSS 1583
- Fluids can e.g. B. air for the interior of a motor vehicle or the
- Centrifugal casting process is produced, using a geometrically defi ⁇
- the outside has a relative tool contact
- the inside has
- Housing part is with the outside or inside of the other housing, ⁇ .
- the two housing parts each have one
- the seal is preferably
- This insert can also be made through the outside and / or the inside
- At least one housing part is double-walled, the inside being at least partially enclosed by the outside from the outside.
- the inside is completely enclosed by the outside, which results in a closed volume in the interior of the housing part. If both housing parts are double-walled, the geometrically precisely defined outer sides of the two housing parts correspond to one another, as a result of which the filter housing has excellent tightness and rigidity.
- the lower housing part is made in one piece with the upper housing part by centrifugal casting.
- the two housing parts are mechanically separated from one another after removal from the tool.
- a piece of waste can also be separated out between the two housing parts.
- the outside and inside are coordinated, which ensures an optimal fit and thus tightness.
- the inventive method for producing a filter housing has at least the steps of filling a plastic powder into a mold, heating, rotating, cooling and opening the mold. After the hollow mold has been opened, the housing part produced is removed from the mold. The housing parts produced are then connected to one another, the outside of one housing part being connected to the outside or inside of the other housing part. With this method, housing parts can be manufactured at low cost, with a good fit and thus tightness.
- the plastic powder being, for. B. can be powdery or granular. Furthermore, the plastic powder can also have another consistency, e.g. B. liquid, which is suitable as a plastic molding compound.
- the plastic powder can still fillers such. B. carbon black, carbon fibers, glass balls or fibers may be added, which increase the mechanical rigidity of the component to be produced or improve the chemical resistance.
- the amount of plastic powder to be introduced depends on the size and the wall thickness of the component to be produced.
- the mold can be sprayed with a release agent or powder
- the hollow mold can be removed.
- the hollow mold can e.g. B.
- Heating can e.g. B. have heating wires.
- the mold is hollow
- the hollow mold must be controlled in such a way that the component is even VSS 1583 is cooled, which prevents excessive distortion caused by the shrinkage.
- the mold can be opened at the mold separations provided and the component can be removed.
- the housing parts can be assembled to form the filter housing, wherein mechanical processing of the housing parts can also take place if necessary.
- Such processing can, for. B. the creation of an opening for the inlet or outlet of the fluid to be cleaned.
- the outside of one component is mounted on the inside or outside of the other component, whereby an optimal sealing of the components to one another is achieved.
- Components which are produced by centrifugal casting, are only in contact with the outside of the mold during the manufacturing process with their outer side.
- the inside of the component has no direct contact with the hollow mold, so the inside results without a defined shape.
- both housing parts are made in one piece in a single mold. After the entire housing part has been removed from the mold, it is separated into two or more housing parts. The individual housing parts are produced by this separation.
- waste pieces can arise which are the result of the production of the entire housing part VSS 1583 have connected individual housing parts. These waste pieces only have the task of connecting the two housing parts to one another in the production of the overall housing part, the transition between the housing parts being designed in such a way that the melt contained in the hollow mold for the tool can flow to any location. Large paragraphs should be avoided here.
- polyethylene or polypropylene is used as the plastic powder. These materials are very inexpensive and can be easily processed using the centrifugal casting process. These materials are also water-resistant.
- the housing parts are connected to one another with tensioning hooks, screws or the like. Due to the detachable connection of the housing parts, the filter element inserted in the filter housing can be easily replaced.
- FIG. 1 shows a schematic illustration of an overall housing part in section
- Figure 2 shows a filter housing in section
- Figure 3 is a double-walled upper housing part in section
- FIG. 4 is a double-walled lower housing part in section.
- VSS 1583
- a total housing part 10 is shown in section.
- the entire housing part 10 is made in one piece in a hollow mold (not shown) as a large hollow part, it having a wall thickness s.
- the wall thickness s is almost constant in the overall housing part 10, it extending between an outer side A and an inner side I.
- the overall housing part 10 has an area which forms the lower housing part 11. Another area is formed by the upper housing part 12.
- the two housing parts 11, 12 are connected to a waste piece 13 along the dash-dotted line.
- the geometries of the housing parts 11, 12 are designed in such a way that, after the waste piece 13 has been removed, they can interlock and be sealingly connected to one another.
- the lower housing part 11 has an insert 14, which is geometrically formed by the outer side A of the lower housing part 11.
- the upper housing part 12 has a receptacle 15 which receives the insert 14 after removal of the waste piece 13.
- the receptacle 15 is geometrically formed by the inside I of the upper housing part 12.
- a filter housing 16 is shown in section. Components corresponding to FIG. 1 are provided with the same reference symbols.
- the filter housing 16 has the upper housing part 12 and the lower housing part 11.
- a filter element 17 is inserted into the lower housing part 11.
- VSS 1583 VSS 1583
- the filter element 17 is sealing between the lower housing part
- the raw area 18 is in the
